ABC13 reported that a neighbor said he witnessed the two victims and their father, Jason Sheats, run out of the house. He said both daughters then collapsed in the street.

The witness added that he saw the mother briefly exit the home and then went back inside to reload her gun. Moments later, the woman returned and shot Madison Sheats in the back.

According to neighbors, when police officers arrived at the scene, the mother was still holding the gun as the two victims laid wounded on the ground nearby.

Officers ordered Christy Sheats to drop the weapon, and when she failed, an officer fired a single shot killing the woman, Click2 Houston reported.

“The cops were behind the trees, cars, and they told the mom to put the gun down, and obviously she did not,” said Fazz Zainuddin, a neighbor of the family.

“She walked towards the body; I think Madison, already on the ground and I guess the cop was afraid that she was going to shoot her again,” Zainuddin said.

Fort Bend County Sheriff, Troy Nehls, stated that the father of the victims witnessed the horrific slayings.

Zainuddin said “one of the deputies heard the husband pleading with the woman, telling her “Don’t do this. They’re our kids.”

Madison Sheats died at the scene, while emergency responders airlifted Taylor Sheats to a hospital, where she later died. The father wasn’t injured but still had to be admitted to the hospital because of distress.

“He was going through a tough time,” Nehls said.

Investigators said deputies have in the past visited the home and neighbors indicated that the parents may have been having marital problems.
